Abstract

Swinging the upstream-side cover part (31) and downstream-side cover part (32) of the check scanning apparatus (1) open on a common support pin (33) opens a U-shaped check transportation path (5). The check transportation path (5) can be opened with a simple single-action operation to remove checks (4) jammed in the check transportation path (5) and for maintenance of the magnetic head (84) and contact image sensors (82 and 83). When the task is completed, the open check transportation path (5) can also be returned to the original closed position by a simple single-action operation. If only those parts that require maintenance are exposed when the check transportation path is open, tasks that require opening the transportation path can be done without damaging other parts and without soiling the operator's fingers.

Description

The present invention relates to a media processing device such as a check reader that is used for reading magnetic ink characters from and imaging sheet media on which information is printed using magnetic ink characters, such as checks, promissory notes, and invoice stubs.
Banks and other financial institutions commonly use check reading devices ("check reader" or "check scanner") to image and read magnetic ink characters from documents such as checks, promissory notes, and invoice stubs, and sort and process the documents based on the result of reading the documents (collectively referred to below as checks). The check reader is usually used on a desk or counter, and the transportation path that carries the check or other document through the check reader is therefore generally U-shaped from the check supply side to the check exit side in order to reduce the size and afford a compact check reader.
In order to remove a check that is jammed inside the U-shaped transportation path, and to clean the magnetic head or scanner (image scanning apparatus) disposed along the transportation path or perform other regular maintenance on this type of check reader, the case is removed to open the transportation path and expose the magnetic head and other parts.
US patent application 2004/0257626 describes a scanner apparatus for scanning bank checks that has this type of arrangement. The part of the case covering the U-shaped transportation path that covers the part where the scanner is located in this check scanner apparatus can be removed. The sensor part of the scanner can pivot on a vertical axis to open and close to the stationary side of the scanner unit. If a check jams in the transportation path, the top part of the case is removed, the sensor part of the scanner is opened, and the check can be removed from the transportation path.
EP-A-0 801 356 discloses a method and apparatus for processing checks having magnetic ink characters printed in a predetermined area on a front side (face) of the check. The predetermined area is scanned with a magnetic head and the resulting detection signals are subjected to a character recognition process. Checks judged to be valid undergo endorsement printing.
However, when the top of the case is removed to expose the transportation path and remove the jammed check, circuit boards and other parts of the transportation path, for example, that are inside and normally covered by the case are also exposed, and the user's fingers, tools, or other objects can easily touch these other parts. Touching these exposed parts can short the circuit board, damage parts, and dirty the fingers. Touching exposed parts with maintenance tools during cleaning or other maintenance of the scanner or magnetic head can also damage those parts. Reinstalling the removed top case to the original position also requires precisely positioning and fitting the case, and installing the case top with a simple single-action is difficult.
It is an object of the present invention to provide a media processing device that enables changing the media transportation path to an open position by means of a simple single-action operation without damaging internal parts and without soiling the fingers of a maintenance person when she/he, for example, removes a sheet medium that is jammed in the media transportation path, and that enables returning the media transportation path to the original position by means of a simple single-action operation without damaging internal parts after the task is completed.
This object is achieved by a media processing device as claimed in the independent claim. The dependent claims define preferred embodiments of the invention.
When the cover of this media processing device opens pivoting on the support pin, the transportation path part also opens. The transportation path part can therefore be opened by means of a simple operation and tasks such as removing jammed sheet media and maintenance of the scanner and other internal parts can be done easily. After the task is completed, the open transportation path portion can be easily returned to the original closed position by simply swinging the cover on the support pin to the closed position. Because the cover can be opened and closed by touching only the cover, there is no damage to internal parts or concern about soiling the operator's fingers.
In the preferred embodiment according to claim 2, when the upstream-side cover and the downstream-side cover that define the U-shaped media transportation path open pivoting on a common support pin, both the upstream-side transportation path portion and the downstream-side transportation path portion of the media transportation path change to an open position. The upstream-side and downstream-side transportation path portions can therefore be opened with a simple single-action operation, and sheet media that is jammed inside can be easily removed. When the task is completed, the upstream-side and downstream-side transportation path portions can also be returned to the original closed position by the simple single-action operation of pivoting the upstream-side cover and the downstream-side cover closed on the common support pin. Furthermore, because the operation that changes the upstream-side and downstream-side transportation path portions to the open position and the operation that returns them to the closed position can be done by touching only the upstream-side cover and the downstream-side cover, there is no damage to internal parts or concern about soiling the operator's fingers.
In the preferred embodiment according to claim 3, opening the upstream-side and downstream-side cover parts separates and opens the transportation rollers and pressure rollers, and sheet media held between these rollers and stuck in the media transportation path can be easily removed.
The preferred embodiment according to claim 4, enables simply opening the cover to easily remove a check or other sheet media that is jammed in the magnetic head area, and to easily clean or perform other maintenance on the magnetic head.
The preferred embodiment according to claim 4, enables simply opening the cover to easily remove a check or other sheet media that is jammed in the image scanning apparatus area, and to easily clean or perform other maintenance on the image scanning apparatus.
If the media processing device is used in a check scanning apparatus, it preferably has a pair of image scanning apparatuses for imaging both sides of the processed checks. In this case a first image scanning device disposed on the device case side of the media transportation path, and a second image scanning device disposed to the cover.
If the media processing device is used in a check scanning apparatus, it preferably also has a print mechanism disposed to the media transportation path for printing on the sheet media so that text such as PROCESSED or an endorsement can be printed on the check, and opening the cover exposes the print mechanism. This arrangement enables simply opening the cover to easily remove a check or other sheet media that is jammed in the print mechanism area, and to easily replace consumables or perform other maintenance on the print mechanism.
In the preferred embodiment according to claim 8, the separate latch mechanisms lock the cover parts in the closed position with good precision, and thereby position the magnetic head, the image scanning apparatus, and the print mechanism disposed to the cover parts with good precision.
A media processing device according to another aspect of the invention has a media transportation path for conveying sheet media, a device case that forms the media transportation path; an cover openably and closably attached to the device case, and a support pin that determines the opening and closing axis of the cover, and is arranged so that a transportation path portion that is at least a part of the media transportation path is formed between the device case and the cover in the closed position, and the transportation path portion changes to an open position when the cover opens from the closed position. The cover has an inside wall part that defines the transportation path portion, a support-pin-side end-face part that is contiguous to the end of the inside wall part on the support pin side, and an outside wall part that is contiguous to the support-pin-side end-face part. The support-pin-side end-face part is defined by a convex circular arc surface centered on the support position, and the inside wall part extends tangentially to the convex circular arc surface from an end of the convex circular arc surface.
Opening the cover of the media processing device according to this aspect of the invention opens at least a part of the transportation path. Because this part of the transportation path can be opened by the simple single-action operation of opening the cover, tasks such as removing a check jammed in the transportation path and maintenance of the image scanning apparatus can be done efficiently.
If part of the device case is the cover, the position of the support pin that defines the pivot axis of the cover must be shifted to the outside of the device case so that the pivot axis end of the cover does not interfere with other parts on the device case side when the cover opens and closes. Furthermore, if the pivot axis end of the cover protrudes into the transportation path when the cover is open, a check that is jammed in this area, for example, will be pressed by the end of the cover, thus making removing the jammed check difficult. It is therefore necessary to move the position of the support pin to the outside of the device case so that the pivot axis end of the cover does not protrude into the transportation path when the cover is open. However, if the support pin is moved to the outside, the part of the device case or the part of the cover covering the support pin must protrude further to the outside than other parts of the case surface. This can detract from the appearance of the device.
As described above, the contour of the end part of the cover on the support pin side is defined by a convex circular arc surface centered on the support pin. The inside wall part extends tangentially to the convex circular arc surface from one end of the convex circular arc surface, and defines the part of the transportation path on the cover side. When the cover is open, the support pin end of the cover will therefore not protrude more to the inside than the same end when the cover is closed. In other words, the support pin end of the cover will not protrude into the transportation path. The sheet media will therefore not be pressed to the device case side as a result of the end of the cover protruding into the transportation path when the cover is opened to remove sheet media that is jammed in the transportation path. Installing an cover also does not impair the appearance of the device because the part of the cover that covers the support pin is flush with the other parts of the case.
Preferably, the end-face part of the cover that opposes the support-pin-side end-face part is defined by a concave circular arc surface that is centered on the support pin and has a radius greater than the radius of the convex circular arc surface.
This arrangement enables providing a small gap between the cover and the device case without the cover interfering with the case when the cover is opened and closed. Furthermore, the outside of the cover and the outside of the device case can be positioned so that the outside surfaces are flush without the cover interfering with the device case when the cover is opened and closed. The part to which the cover is disposed can therefore be rendered with a more attractive appearance.
If the invention is applied to a media processing device that is constructed so that a U-shaped media transportation path can be opened by means of an upstream-side cover and a downstream-side cover that pivot open and closed on a common support pin, the arrangement defined in claim 11 is desirable.
In this case, when the upstream-side cover and the downstream-side cover that define the U-shaped media transportation path open pivoting on a common support pin, both the upstream-side transportation path portion and the downstream-side transportation path portion of the media transportation path change to an open position. The upstream-side and downstream-side transportation path portions can therefore be opened with a simple single-action operation, and sheet media that is jammed inside can be easily removed. When the task is completed, the upstream-side and downstream-side transportation path portions can also be returned to the original closed position by the simple single-action operation of pivoting the upstream-side cover and the downstream-side cover closed on the common support pin. Furthermore, because the operation that changes the upstream-side and downstream-side transportation path portions to the open position and the operation that returns them to the closed position can be done by touching only the upstream-side cover and the downstream-side cover, there is no damage to internal parts or concern about soiling the operator's fingers.
Furthermore, because the contours of the support pin end parts of the upstream-side cover and the downstream-side cover are formed as described above, the ends of the cover parts on the support pin side will not protrude into the transportation path when the cover parts are opened. The sheet media will therefore not be pressed by these ends of the cover parts to the device case side when the cover parts are opened in order to remove sheet media jammed in the transportation path.
The cover parts can also be disposed with a narrow gap therebetween without the support pin side ends of the cover parts interfering with each other when the cover parts are opened and closed. In addition, the outside surfaces at the support pin end of the cover parts can be rendered flush with each other with no parts protruding more to the outside than other parts of the case surface. This affords a cleaner appearance.
The media processing device according to the invention can also be used as a check scanning apparatus for reading and processing checks, promissory notes, and invoice stubs, for example.

A preferred embodiment of a media processing device according to the present invention is described below with reference to the accompanying figures.

General configuration

FIG. 1 is an external perspective view of a check processing apparatus as a preferred embodiment of a media processing device according to the invention. FIG. 2 is an external perspective view of the check scanning apparatus 1 from the opposite side as shown in FIG. 1. FIG. 3 is a plan view of the check scanning apparatus 1.
As shown in the figures, the check processing apparatus according to this embodiment is described as a check scanning apparatus 1 that has a case 2 and an cover 3 changeable between an open and a closed state. A check transportation path 5 for conveying checks 4 is formed between the case 2 and the cover 3.
The check transportation path 5 is a narrow vertical slot that curves in a basically U-shaped configuration when seen from above. The end of the check transportation path 5 on the upstream side of the check transportation direction is connected through a check infeed path 6, which is a narrow vertical slot, with a check supply unit 7, which is a wide vertical slot. The downstream end of the check transportation path 5 is connected through left and right diversion paths 8 and 9 to left and right first and second check discharge units 11 and 12. The diversion paths 8 and 9 are narrow vertical slots branching to the left and right from the check transportation path 5. The first and second check discharge units 11 and 12 are relatively wide vertical slots.
As shown in FIG. 1, the check 4 has an MICR line 4A printed along the long bottom edge on the front 4a of the check 4. Also recorded on the front 4a against a patterned background are the check amount, payer and payee, various numbers, and the payer signature. An endorsement is recorded on the back 4b of the check 4. The checks 4 are loaded in the check supply unit 7 with the tops and bottoms of the checks aligned and the fronts 4a of the checks facing the outside of the U-shaped check transportation path 5.
When a check 4 is delivered from the check supply unit 7 through the check infeed path 6 and then conveyed along the check transportation path 5, the MICR line 4A printed on the front 4a is read and the front 4a and back 4b of the check 4 are imaged. If this information is scanned correctly, PROCESSED or other text is printed on the front or back, and the check 4 is then diverted and discharged into the first check discharge unit 11. If the check 4 cannot be read or a scanning error occurs, nothing is printed and the check 4 is diverted and discharged into the second check discharge unit 12.
FIG. 4 is an external perspective view of the check scanning apparatus 1 from the same side as shown in FIG. 1 and with the cover 3 open for access to the transportation path. FIG. 5 is a perspective view of the check scanning apparatus 1 as shown in FIG. 4 but from the opposite side (that is, the same side as shown in FIG. 2). FIG. 6 is a plan view of the check scanning apparatus 1 with the cover 3 open as shown in FIG. 4. FIG. 7 shows the part of the cover 3 where the cover 3 hinges to open and close.
As shown in the accompanying figures, the case 2 has a middle case portion 22, right and left side case portions 23 and 24, and a divider 25 disposed between the middle case portion 22 and the side case portion 24. The middle case portion 22 has a vertical outside wall portion 21 that is contoured to follow the U-shaped check transportation path 5. The check supply unit 7 is rendered between the middle case portion 22 and the side case portion 23. The divider 25 divides the space between the middle case portion 22 and the side case portion 24 into left and right sides forming the first and second check discharge units 11 and 12.
The outside wall portion 21 of the middle case portion 22 facing the right and left side case portions 23 and 24 is covered by the cover 3 on both the left and the right side.
The cover 3 includes an upstream-side cover part 31 on the side case portion 23 side and a downstream-side cover part 32 on the side case portion 24 side. The upstream-side portion 5a of the check transportation path 5 is rendered between the middle case portion 22 and the upstream-side cover part 31, and the downstream-side portion 5b of the check transportation path 5 is rendered between the middle case portion 22 and the downstream-side cover part 32.
The proximal end portion 31 a of the upstream-side cover part 31 and the proximal end portion 32a of the downstream-side cover part 32 are the pivot axis ends of the cover 3, and are attached to a vertical support pin 33 that is disposed to the case 2 so that the upstream-side cover part 31 and the downstream-side cover part 32 can open and close to the right and left. The support pin 33 is disposed at a position substantially at the midpoint of the U-shaped check transportation path 5 in the transportation direction. As shown in FIG. 4 to FIG. 6, when the upstream-side cover part 31 and the downstream-side cover part 32 open to the right and left, the upstream-side transportation path portion 5a and the downstream-side transportation path portion 5b are also opened.

Transportation mechanism

FIG. 8 describes the transportation mechanism of the check scanning apparatus 1.
An infeed roller 41 and a pressure member 42 are disposed to the check supply unit 7. The infeed roller 41 feeds checks 4 which are loaded in a stack in the check supply unit 7 one at a time into the check infeed path 6. The pressure member 42 presses the checks 4 against the infeed roller 41.
Disposed to the check infeed path 6 for feeding the checks 4 delivered by the infeed roller 41 into the check transportation path 5 are a separation pad 43 and a pair of separation rollers including a separation roller 44 and a retard roller 45. The separation pad 43, separation roller 44, and retard roller 45 render a separation mechanism for separating and feeding the checks 4 one at a time from the stack into the check transportation path 5. The infeed roller 41, the separation roller 44, and the pressure member 42 are driven by a common infeed motor 46.
The transportation mechanism for conveying the checks 4 delivered by the infeed roller 41 through the check transportation path 5 includes a transportation motor 47, a drive roller 48 mounted on the rotating shaft of the transportation motor 47, a set of transportation rollers 51 to 57 disposed along the check transportation path 5, and a set of pressure rollers 61 to 67 that are pressed against and rotate with the transportation rollers 51 to 57. Rotation of the pressure roller 67 is transferred through a transfer gear 68 to a discharge roller 69. An endless belt 49 transfers rotation of the transportation motor 47 to the transportation rollers 51 to 57. The endless belt 49 moves along an endless loop from the drive roller 48 past a guide roller 71, a transportation roller 56, a guide roller 72, a transportation roller 57, transportation rollers 51 and 52, guide rollers 73 and 74, transportation rollers 53, 54, and 55, and back to the drive roller 48.
The transportation rollers 51 to 54 are located at the upstream end, the middle, and the downstream part of the upstream-side transportation path portion 5a. The transportation rollers 55 and 56 are located at the upstream part and the middle of the downstream-side transportation path portion 5b, and the transportation roller 57 is located where the checks are discharged into the second check discharge unit 12. Discharge roller 69 is located where the checks are discharged into the first check discharge unit 11.
A magnet 81 for magnetizing the magnetic ink characters is disposed between the transportation rollers 51 and 52 in the upstream-side transportation path portion 5a. A front contact image sensor 82 is disposed as the front image scanner, and a back contact image sensor 83 is disposed as a back image scanner, between the transportation rollers 52 and 53. A magnetic head 84 for magnetic ink character reading and a pressure roller 85 for pressing the checks 4 to the magnetic head 84 are disposed between transportation rollers 53 and 54.
A print mechanism 86 is disposed on the downstream side of the transportation roller 56 in the downstream-side transportation path portion 5b. The print mechanism 86 can move between a printing position applying pressure to the check 4 and a standby position retracted from this printing position by means of a drive motor (not shown in the figure). The print mechanism 86 can also be rendered as a stamp mechanism that is pushed by a plunger to print (stamp) the check 4.
Various sensors for check transportation control are also disposed to the check transportation path 5.
A paper length detector 91 for detecting the length of the conveyed check 4 is located near the magnet 81.
A multifeed detector 92 for detecting if two or more checks 4 are being fed together is located near the reading position 84A of the magnetic head 84.
A jam detector 93 is located at a position on the upstream side of the transportation roller 55. A check is known to be jammed in the check transportation path 5 if the jam detector 93 detects a check 4 continuously for a prescribed time or longer.
A print detector 94 for detecting the presence of a check 4 printed by the print mechanism 86 is located on the upstream side before the transportation roller 56.
A discharge detector 95 for detecting the discharged check is disposed to the diversion paths 8 and 9 where the check transportation path 5 branches to the first and second check discharge units 11 and 12.
A flapper 96 that is driven by a drive motor not shown to switch the discharge path is disposed on the upstream side of the diversion paths 8 and 9. The flapper 96 selectively switches the downstream end of the check transportation path 5 to the first check discharge unit 11 or the second check discharge unit 12, and guides the check 4 to the selected discharge unit.
The distance from the reading position 84A of the magnetic head 84 in the check transportation path 5 to the printing position 86A of the print mechanism 86 is substantially equal to the length of the long side (transportation direction) of the check 4 to be scanned in this embodiment of the invention. As a result, when the leading end of the check 4 reaches the printing position 86A, the trailing end has just passed the reading position 84A of the magnetic head 84. The check 4 is therefore sequentially conveyed by the transportation roller 54 and the pressure roller 64, and by the transportation roller 55 and the pressure roller 65, as the magnetic head 84 reads the magnetic ink characters. The check 4 is also conveyed sequentially by the transportation roller 53 and pressure roller 63, by the transportation roller 54 and the pressure roller 64, and by the transportation roller 55 and the pressure roller 65 as the contact image sensors 82 and 83 image the front and back of the check 4.

Control system

FIG. 9 is a block diagram showing the control system of the check scanning apparatus 1. The control system of the check scanning apparatus 1 includes a control unit 100 that is built around a CPU and has a RAM and a ROM. The control unit 100 is connected to a host computer system 103 through a communication cable 102 but may of course be connected by other means such as wirelessly. The computer system 103 has a display unit 103a and input/output devices such as a keyboard, mouse, or other operating unit 103b. Check scanning operation start commands and other commands are input from the computer system 103 to the control unit 100.
When a scanning operation start command is received, the control unit 100 drives the infeed motor 46 and transportation motor 47 to feed the checks 4 one at a time to the check transportation path 5 and convey the supplied check 4 through the check transportation path 5. The front image data, back image data, and magnetic ink character data captured from the check 4 by the front contact image sensor 82, the back contact image sensor 83, and the magnetic head 84 are input to the control unit 100. This data is then supplied to the computer system 103 for image processing and character recognition processing. The computer system 103 also determines if the check 4 was scanned normally, and the result is supplied to the control unit 100. Based on this result the control unit 100 controls driving the print mechanism 86 and the flapper 96. Note that these processes that are performed by the computer system 103 can alternatively be executed by the control unit 100 of the check scanning apparatus 1 instead of by the computer system 103.
The control unit 100 controls conveying the check 4 based on the detection signals from the paper length detector 91, the multifeed detector 92, the jam detector 93, the print detector 94, and the discharge detector 95 that are disposed along the check transportation path 5. An operating unit 105 including a power supply switch and other switches is also disposed to the case 2 and connected to the control unit 100.

Check processing operation

FIG. 10 is a flow chart describing the operation of the control unit 100 of the check scanning apparatus 1. The scanning operation is described next with reference to this flow chart.
When the operator inputs a start scanning command from the operating unit 103b of the host computer system 103, the infeed motor 46 causes the infeed roller 41 to turn and the pressure member 42 to move and press the checks 4 against the infeed roller 41. One or more checks 4 are thus advanced by the infeed roller 41. The separation mechanism (separation pad 43, separation roller 44, and retard roller 45) disposed to the check infeed path 6 separates and feeds the checks 4 delivered into the check infeed path 6 one by one into the check transportation path 5 (steps ST1 and ST2).
When the paper length detector 91 detects the leading end of the conveyed check 4, the transportation motor 47 is driven to rotationally drive the transportation rollers 51 to 57. The supplied check 4 is passed sequentially to the transportation rollers 51 to 56 and conveyed through the check transportation path 5 (step ST3). The front and back of the check 4 are imaged and the magnetic ink characters are read by the front contact image sensor 82, the back contact image sensor 83, and the magnetic head 84, respectively, as the check 4 is conveyed (step ST4).
The captured data is then sent through the communication cable 102 (or other means) to the host computer system 103 (step ST5). The computer system 103 processes the scanned front image, back image, and magnetic ink character data, and determines if the check was read correctly. If the check 4 is fed with the top and bottom upside down, the magnetic ink characters cannot be recognized, and a read error results. If the check 4 is fed with the front and back reversed, the magnetic ink character data cannot be acquired and a read error results. If the check 4 is creased, torn, or skewed when fed so that a portion of the magnetic ink characters cannot be read, a read error results. A read error also results if the check amount or other prescribed information cannot be recognized from the front and back image data because the check 4 is creased, torn, or skewed when fed.
Referring again to the check scanning apparatus 1 side, when the leading end of the conveyed check 4 reaches the printing position 86A of the print mechanism 86, the transportation mechanism pauses conveying the check 4 (step ST6). The position of the leading end of the conveyed check 4 is obtained by counting the number of steps the transportation motor 47 is driven from when the paper length detector 91 detects the leading end of the check 4. When conveying the check 4 stops, the check scanning apparatus 1 waits for the scanning determination result from the computer system 103 (step ST7).
If the received scanning determination result indicates that the check 4 was scanned correctly, conveying the check 4 resumes and the print mechanism 86 is simultaneously moved to the printing position (steps ST8 and ST9). The print mechanism 86 prints PROCESSED, for example, on the check 4, and the check 4 is directed into the first check discharge unit 11 by the flapper 96 (step ST10). Driving the transportation mechanism stops after the discharge detector 95 detects the trailing end of the check 4 (steps ST11 and ST12). Feeding and processing the next check 4 then starts.
If the received scanning determination result indicates that the check 4 was not scanned correctly (step ST8), conveying the check 4 resumes (step ST13) and the flapper 96 changes position. The print mechanism 86 is held in the standby position and does not print on the check 4. The check 4 is thus diverted by the flapper 96 and discharged into the second check discharge unit 12 (step ST14). Driving the transportation mechanism stops after the discharge detector 95 detects the trailing end of the check 4 (steps ST11 and ST12), and the operation for scanning the next check 4 then starts.
If the multifeed detector 92 detects a check multifeed state, an interrupt process is executed to immediately stop check transportation, signal a check transportation error to the operator by driving a warning indicator on the operating unit 105, report the transportation error to the computer system 103, and then wait until the checks are removed from the check transportation path 5 and the checks are reset to the starting position. A similar interrupt process is executed if the jam detector 93 detects that a check is jammed in the check transportation path 5.

Cover

The upstream-side cover part 31 and the downstream-side cover part 32 that render the cover 3 are described below with reference to FIG. 1 to FIG. 7.
The upstream-side cover part 31 and the downstream-side cover part 32 are normally locked in the closed position by separate latching mechanisms. As shown in FIG. 4 and FIG. 6, the latch mechanism of the upstream-side cover part 31 includes a cover-side strike 34 and a catch 35. The cover-side strike 34 is formed at the bottom of the distal end 31 b of the upstream-side cover part 31. The catch 35 is disposed retractably into the end face 23a of the side case portion 23 at a position opposite the cover-side strike 34. The catch 35 is urged in the protruding direction by a spring force not shown. A sliding release button 36 for releasing the latch is disposed to the outside of the side case portion 23.
When the sliding release button 36 is slid against the spring force, the catch 35 separates from the cover-side strike 34 and the upstream-side cover part 31 can swing open to the side pivoting on the support pin 33. When the open upstream-side cover part 31 is then closed, the corner of the cover-side strike 34 protruding from the distal end 31 b pushes the catch 35 in as the cover-side strike 34 moves to the closed position. When the upstream-side cover part 31 reaches the closed position, the catch 35 engages the cover-side strike 34 and the upstream-side cover part 31 is locked closed. An identical latch mechanism (including a cover-side strike 37, a catch 38, and a sliding release button 39) is disposed to the downstream-side cover part 32.
Referring to FIG. 4, FIG. 5, and FIG. 6, the front contact image sensor 82 and the pressure rollers 61 to 64 that are disposed to the upstream-side transportation path portion 5a are assembled to the upstream-side cover part 31. The pressure rollers 65 and 66 disposed to the downstream-side transportation path portion 5b are assembled to the downstream-side cover part 32.
When the upstream-side cover part 31 opens the upstream-side transportation path portion 5a opens and the scanning surfaces of the front contact image sensor 82 and the back contact image sensor 83 are exposed. The magnetic head 84 that is disposed on the case 2 side is also exposed.
Opening the downstream-side cover part 32 similarly opens the downstream-side transportation path portion 5b, and exposes the print mechanism 86 that is disposed on the case 2 side.
In this embodiment of the invention the magnetic head 84 and the pressure roller 85 are both disposed on the case 2 side, and the magnetic head 84 is positioned so that it can read the MICR line 4A on the check 4. Alternatively, the pressure roller 85 can be disposed on the upstream-side cover part 31 side, and the magnetic head 84 can be disposed on the case 2 side at a position opposite the pressure roller 85. The magnetic head 84 is more exposed with this arrangement when the upstream-side cover part 31 is open, and therefore makes maintenance easier. In this case the front contact image sensor 82, the back contact image sensor 83, and the print mechanism 86 are located on the opposite side of the check transportation path 5.
If a check 4 becomes jammed in the check transportation path 5 of a check scanning apparatus 1 having this cover 3, the right and left sliding release buttons 36 and 39 are operated and the right and left upstream-side cover part 31 and downstream-side cover part 32 open to the right and left pivoting on the support pin 33. When the latch mechanism is released, the pressure of the pressure rollers against the transportation rollers pushes the upstream-side and downstream- side cover parts 31 and 32 open. A torsion spring or other urging member could also be mounted on the support pin 33 to urge the upstream-side and downstream- side cover parts 31 and 32 open. With either arrangement, however, the simple single-action operation of sliding the sliding release buttons 36 and 39 can open the cover parts.
As shown in FIG. 4 to FIG. 6, opening the upstream-side and downstream- side cover parts 31 and 32 opens the check transportation path 5 (upstream-side transportation path portion 5a and downstream-side transportation path portion 5b). A jammed check 4 can therefore be easily removed. After removing the jammed check, the upstream-side and downstream- side cover parts 31 and 32 can also be closed with a simple single-action operation.
The upstream-side and downstream- side cover parts 31 and 32 can also be opened in the same way for maintenance of the magnetic head 84, the front contact image sensor 82, the back contact image sensor 83, and the print mechanism 86, including cleaning and replacement of consumables. Because opening the cover parts exposes the magnetic head 84, the front contact image sensor 82, the back contact image sensor 83, and the print mechanism 86, maintenance tasks can be done easily. Damage to parts other than these parts requiring maintenance can also be avoided by locating them inside the case 2 instead of where they will be exposed when the cover 3 is opened.
The check transportation path 5 can thus be opened by the simple operation of swinging the upstream-side cover part 31 and the downstream-side cover part 32 open on a common support pin 33, and the check transportation path 5 can be returned to the normal closed position by the simple operation of swinging these cover parts closed on the common support pin 33. The operation of opening the check transportation path 5 is thus simple, damage to parts not subject to regular maintenance in the check scanning apparatus 1 can be prevented during maintenance, and the fingers will not be soiled during maintenance.
The upstream-side and downstream- side cover parts 31 and 32 can also be held with good precision in their respective closed positions because they are locked in the closed positions by separate latch mechanisms.

Configuration of the support pin end parts of the cover

The contours of the proximal end portions 31 a and 32a of the upstream-side cover part 31 and the downstream-side cover part 32, that is, the contours of the ends at the support pin 33, are described next with reference to FIG. 7. Note that the support pin 33 is not shown in FIG. 7 to provide a better view of the shape of the proximal end portions 31 a and 32a.
The upstream-side cover part 31 has an inside surface part 311 that defines part of the upstream-side transportation path portion 5a, an upstream-side end-face part 312 (support-pin-side end-face part) that continues from the support pin 33 side end of the inside surface part 311, and a outside surface part 313 that continues from the upstream-side end-face part 312.
The downstream-side cover part 32 has an inside surface part 321 that defines part of the downstream-side transportation path portion 5b, a downstream-side end-face part 322 (support-pin-side end-face part) that continues from the support pin 33 side end of the inside surface part 321, and an outside surface part 323 that continues from the downstream-side end-face part 322.
As will be apparent from FIG. 2, FIG. 5, and FIG. 7, the upstream-side end-face part 312 of the upstream-side cover part 31 has upstream-side convex surfaces 314 and 315, which center on the support pin 33 and are formed at the top and bottom axial ends of the support pin 33, and an upstream-side concave surface 316, which is rendered between the upstream-side convex surfaces 314 and 315 and is also centered on the support pin 33.
The contours of the downstream-side end-face part 322 complement the contours of the upstream-side end-face part 312. More particularly, the downstream-side end-face part 322 of the downstream-side cover part 32 includes downstream-side concave surfaces 324 and 325 and a downstream-side convex surface 326. The concave surfaces 324 and 325 center on the support pin 33 and are formed at the top and bottom axial ends of the of the support pin 33. The convex surface 326 is formed between the concave surfaces 324 and 325 and is also centered on the support pin 33.
The top and bottom upstream-side convex surfaces 314 and 315 are circular arc surfaces with a central angle of approximately 180 degrees. The downstream-side concave surfaces 324 and 325 oppose the top and bottom upstream-side convex surfaces 314 and 315 with a prescribed gap therebetween, and the convex surface 326 is similarly disposed opposite the concave surface 316 with a prescribed gap therebetween. The upstream-side convex surfaces 314 and 315 and the convex surface 326 are defined by the same convex circular arc surfaces, and the downstream-side convex surface 326 is also a circular arc surface with a central angle of approximately 180 degrees.
The upstream-side concave surface 316 and the downstream-side concave surfaces 324 and 325 are defined by identical concave circular arc surfaces. The radius of these concave circular arc surfaces is slightly greater than the radius of the convex circular arc surfaces that define the upstream-side convex surfaces 314 and 315 and the downstream-side convex surface 326. These concave circular arc surfaces have an arc with a central angle less than 180 degrees, and in this embodiment of the invention are curved surfaces with a central angle of approximately 90 degrees.
At the proximal end portion 31a of the upstream-side cover part 31, the inside surface part 311 that is part of the upstream-side transportation path portion 5a continues tangentially from the ends of the upstream-side convex surfaces 314 and 315. These surfaces therefore do not project into the upstream-side transportation path portion 5a when the upstream-side convex surfaces 314 and 315 rotate to the inside on the support pin 33.
The inside surface part 321 defining part of the downstream-side transportation path portion 5b at the proximal end portion 32a of the downstream-side cover part 32 likewise continues tangentially from the ends of the downstream-side convex surface 326. The downstream-side convex surface 326 therefore does not project into the downstream-side transportation path portion 5b when it rotates on the support pin 33 to the inside.
As will be understood from FIG. 3 and FIG. 6, when the contours of the proximal end portions 31 a and 32a are set as described above and the upstream-side cover part 31 and the downstream-side cover part 32 are opened, the proximal end portions 31a and 32a do not protrude farther to the inside than when the proximal end portions 31 a and 32a are in the closed position. More specifically, the upstream-side convex surfaces 314 and 315 of the proximal end portion 31 a and the convex surface 326 of the proximal end portion 32a are described by circular arc surfaces centered on the support pin 33.
In addition, at the proximal end portion 31 a of the upstream-side cover part 31, the inside surface part 311 describing part of the upstream-side transportation path portion 5a continues tangentially to the ends of the upstream-side convex surfaces 314 and 315. As a result, when the upstream-side convex surfaces 314 and 315 rotate to the inside centered on the support pin 33, that is, when the upstream-side cover part 31 opens, these convex surfaces 314 and 315 do not protrude into the upstream-side transportation path portion 5a.
Likewise at the proximal end portion 32a of the downstream-side cover part 32, the inside surface part 321 describing part of the downstream-side transportation path portion 5b extends tangentially to the end of the convex surface 326. As a result, when the downstream-side convex surface 326 rotates to the inside centered on the support pin 33, that is, when the downstream-side cover part 32 opens, the downstream-side convex surface 326 does not protrude into the downstream-side transportation path portion 5b.
As described above, the proximal end portions 31 a and 32a do not protrude into the transportation path portions 5a and 5b when the upstream-side cover part 31 and the downstream-side cover part 32 are open. Therefore, when the cover parts 31 and 32 are opened in order to remove a check 4 that is stuck in the transportation path portions 5a or 5b, the check 4 will not be pressed against the outside wall portion 21 on the case 2 side as a result of the proximal end portions 31a and 32a protruding into the transportation path portions 5a and 5b. The proximal end portions 31a and 32a will therefore not interfere with removing a jammed check 4.
Furthermore, when both cover parts 31 and 32 are closed, the gap therebetween is minimal, foreign objects will not get inside, and the appearance is not impaired. Yet further, because the outside surface parts 313 and 323 of the cover parts 31 and 32 are substantially flush, a good appearance is maintained, unlike when the surfaces are not in alignment.
The proximal end portions 31a and 32a of both cover parts 31 and 32 are assembled to mate, and the mutually opposed parts thereof are defined by the concentric upstream-side convex surfaces 314 and 315 and downstream-side concave surfaces 324 and 325, and by the upstream-side concave surface 316 and the downstream-side convex surface 326. The cover parts 31 and 32 can therefore open and close without interfering with each other even though the gap between the end portions is small.
As described above, if a check 4 jams in the check transportation path 5 of a check scanning apparatus 1 according to this embodiment of the invention, the right and left sliding release buttons 36 and 39 can be operated to release and open the right and left upstream-side cover part 31 and downstream-side cover part 32 to the right and left pivoting on the support pin 33. When the latch mechanism is released, the pressure of the pressure rollers 61 to 66 pressed against the transportation rollers 51 to 56 pushes the upstream-side and downstream- side cover parts 31 and 32 open. A torsion spring or other urging member could also be mounted on the support pin 33 to urge the upstream-side and downstream- side cover parts 31 and 32 open. With either arrangement, however, the simple single-action operation of sliding the sliding release buttons 36 and 39 can open the cover parts.
As shown in FIG. 4 to FIG. 6, opening the upstream-side and downstream- side cover parts 31 and 32 opens the check transportation path 5 (upstream-side transportation path portion 5a and downstream-side transportation path portion 5b). A jammed check 4 can therefore be easily removed. After removing the jammed check, the upstream-side and downstream- side cover parts 31 and 32 can also be closed with a simple single-action operation.
The upstream-side and downstream- side cover parts 31 and 32 can also be opened in the same way for maintenance of the magnetic head 84, the front contact image sensor 82, the back contact image sensor 83, and the print mechanism 86, including cleaning and replacement of consumables. Because opening the cover parts exposes the magnetic head 84, the front contact image sensor 82, the back contact image sensor 83, and the print mechanism 86, maintenance tasks can be done easily. Damage to parts other than these parts requiring maintenance can also be avoided by locating them inside the case 2 instead of where they will be exposed when the cover 3 is opened.
The contours of the proximal end portions 31a and 32a (end parts on the support pin side) of the upstream-side cover part 31 and the downstream-side cover part 32 are described by convex circular arc surfaces and concave circular arc surfaces centered on the support pin 33. The inside surface part 311 that defines part of the upstream-side transportation path portion 5a on the upstream-side cover part 31 extends tangentially from the ends of the upstream-side convex surfaces 314 and 315. Likewise, the inside surface part 321 that defines part of the downstream-side transportation path portion 5b extends tangentially from the end of the convex surface 326.
Therefore, when the cover parts 31 and 32 are opened, the proximal end portions 31 a and 32a will not protrude farther to the inside than when in the closed position. More specifically, the proximal end portions 31a and 32a at the support pin 33 side will not protrude into the transportation path portions 5a and 5b. Therefore, when the cover parts 31 and 32 are opened in order to remove a check 4 that is stuck in the transportation path portions 5a or 5b, the check 4 will not be pressed against the outside wall portion 21 on the case 2 side by the proximal end portions 31 a and 32a of the cover parts 31 and 32.
In addition, the outside surface parts 313 and 323 of the proximal end portions 31a and 32a of the cover parts 31 and 32 form a flat, flush surface, and thus afford a better appearance than when the part that covers the support pin 33 protrudes further to the outside.
Furthermore, because the proximal end portions 31a and 32a are assembled with concave circular arc surfaces opposing concentrically matching convex circular arc surfaces, the gap therebetween can be small without opposing surfaces interfering with each other when opening and closing. The cover parts 31 and 32 that are provided for opening the check transportation path 5 in this embodiment of the invention will therefore not impair the appearance of the check scanning apparatus 1.
The present invention can be used in media processing devices other than check scanning apparatuses for processing checks, promissory notes, and invoice stubs. The invention can, for example, be used in a scanner apparatus for processing tickets such as entrance tickets.
